Delight, very healthy looking semps. Some of the offsets look like they might be mature enough. The best way to tell is on those larger offsets, look to see if you see small white roots starting to form. If so you can transplant them.

Delight, I see you don't have any Profile information. Like the area you live in, and the growing zone. First name is great also if you don't mind doing that?
Here are two links to getting some free acorns for the June Raffle that is not a raffle. You can win some amazing prizes. Hope you can participate.
This link if you fill in some information on your Profile will earn you acorns. Baja will give them to you. The thread "Shakin' the old tree" in The June 2017 Not-A-Raffle-Raffle!
And this link is to the Raffle. List all the prizes and instructions. https://garden.org/ideas/view/...

Hi Victoria and welcome... To answer your question about the stem (stolon) that attaches chicks to mother plant, I keep it attached to the chick because it helps anchor the new planting until it develops more roots, but I bet people have different ways of doing this.

Hi Victoria
Welcome to the forum.
I will be very interested to see how your semps do over the winter. I think if they are under some snow they should be fine even @ -30 C. My sister grows beautiful lilies in Gunn (north of Edmonton).
You don't have to cut the babies off. You can just give it a little tug and the stem should detach from the mother. Some semps grow a few roots on the stem but most of the roots grow from the bottom of the rosette. If you just press the rosette,gently onto a free draining soil mix, it will root all by itself. Greg's advice about keeping at least some of the stem and sticking it into the soil is what I do as well. It helps stablize the chick till it roots in. I see there is a tag in your pot.
Does your Semp have a name?

Hi! Thank you and Greg for the advice on keeping the stem. Some are definitely ready to re-pot. Here's a photo of the tag.
